It is the sodium salt of glucogentate, containing 7 hydroxyl groups and 1 carboxylate sodium group in the molecule. Its chemical properties are stable and it easily forms chelates with metal ions.
Physical properties: In its normal state, it is a white to pale yellow crystalline or powder form. The melting point is approximately 177°C, the boiling point is about 727.8°C (760 mmHg), and the density is approximately 1.45 g/cm³ at 20°C. It is highly soluble in water, and the aqueous solution is weakly alkaline; it is almost insoluble in organic solvents such as ethanol.
Sodium glucoheptonate CAS 31138-65-5 Use
Industrial chelating agent: As a polyvalent chelating agent, it is used in water treatment, electroplating and other processes. It can effectively inhibit the precipitation of metal ions and prevent the decomposition of hydrogen peroxide catalyzed by trace metal ions.
Pharmaceutical field:
Radioactive imaging: As a labeling kit for Tc-99m, it is used for radioactive nuclide imaging of the kidneys and the brain (especially for brain tumors).
Ingredients: These are the supplementary materials that can serve as mineral supplements, helping to enhance the absorption of elements such as calcium and iron.
Other applications: Used in detergent formulations to enhance cleaning power, and as a chelating agent in cosmetics.
Sodium glucoheptonate CAS 31138-65-5 safety
Safety: It is a low-toxic substance and has high safety for both oral intake and skin contact. Safety instructions are S24/25 (Prevent skin and eye contact).
Storage: Store in a cool, dry place to prevent moisture absorption and crystallization. For some reagent-grade products, it is recommended to be stored under an inert atmosphere at -20°C in a freezer.
